A commuter office lady and an adolescent student are on a crowded bus. Every time the bus shakes, the office lady's plump ass wrapped in a tight skirt stimulates the sensitive crotch of the student, making him feel a bulging erection. The excited woman's hand reaches out to grab his dick. The student, whose sexual desire can't be contained, pushes his pantyhose aside and inserts his dick so the other passengers don't notice!
